Why do clouds form?

Question

According to chemistry and stuff like that, particles will move from an area of higher concentration to lower concentration. So why doesn't the water in the air just spread out equally? What makes the water form a cloud?

Answer 1

Clouds form when upward flowing air, which cools from expansion, can no longer contain all of the water vapor it holds. Some of the vapor condenses into cloud droplets (or ice crystals, if the air is cold enough), forming a cloud. (Water vapor is invisible…..cloud droplets are visible). The cloud then has two choices…it can either re-evaporate into water vapor, or the cloud particles can combine together to form precipitation, which then fall to the ground. For the average precipitation system, about one-half of the water will grow large enough to fall to the ground as precipitation, while the other half will remain as small droplets and eventually re-evaporate into water vapor.

Answer 2

pollution causes water molecules to gather around condensation nucleui like the small particle-dust,pollution, etc-around which the water condensesand gather to make a big amss. This float around up in the atmosphere along the direction of wind for a while. lastly CLOUDS fall to earth different forms like rain, hailstone, etc

Answer 3

pollution causes water molecules to gather around condensation nucleui (the small particle-dust,pollution, etc-around which the water condenses) this float around up in the atmosphere for a while *CLOUDS* and then fall to earth //rain//

Answer 4

Pressure in atmosphere compreses the water vapor into a cloud and when it get to be too much ...it dumps it ..Rain, snow .sleet

Answer 5

Coalescence causes water droplets to from bonds that from happening.
